PUMP. Application filed January 21, 1927. Serial No. 162,518.

The present invention relates to a pump extends from the tubular portion 1a lateralparticularly adapted for usewith barrels ly thereof so that the hose or the like may and like containers forjtorcing liquid therebe connected therewith for leading the liqfrom. r

Another important object of the invention place. A pipe 19 depends downwardly from lies in the provision of a pump for use with the central portion of the head or cap 11 vessels containing liquid so that pressure through the tubular member ll and has its may be created above the liquid to force the lower end bent laterally to extend through liquid from the vessel and means whereby an opening 20in the portion 16. A spring 65 the pressure may be released when desired. pressed check valve is mounted in the pipe 1 A still "further important object of the in" 19 to normallyclose the opening 13. vention lies in the provision of a pumping Thenumeral 23 denotes a hollow plunger mechanism that is exceedingly simple in its rod slidable through the stufling box and construction, inexpensive to manufacture, having a flexible plunger 241 mounted on its 70 strong and durable, thoroughly reliable and inner lower end in abutment with thebrac clficient in operation, and otherwise well ing disk which is smaller in diameter adapted to the purpose -for which it is dethan the plunger. The upper portion of thesigned. cylinder is provided with a vent opening 26.

With the above and other objects in view The upper outer end of the plunger rod 23 5 20 as will appear as the description proceeds, has a bracket'27 mountedthereon and pivthe invention resides in certain novel teaotally engaged with the lever 28. A rod 29 tures of construction, and in the combinais pivotally engaged as at with one end tion and arrangement of parts as will be oi the lever 28 and the other end is pivotally hereinafter more fully described and engaged as at 31- with the bottom of the cap 5 l i d, 11. A spigot 32 is mounted on the upper In the drawing 1- end of the hollow plunger rod 23. A spider Figure 1 is a sectional view of the pump 33 is mounted in the lower end of the hollow embodying the features of my invention and plunger rod 23 as is clearly shown in Fig. 2 showing the same associated with a vessel and has a pin 3 1 projecting therefrom becontaining fluid, low the lower end of said rod, so that when Fig. 2 is an enlarged detail sectional. view the plunger is in its normal position said through the pump showing the air pressure pin 34 will engage the check valve 21 and rerelease. lease it from the opening 13 to leave any uid pumped from the tank to any desired 6" Referring to the drawing in detail it will air pressure in the top of the tank 5 through no r be seen that 5 denotes a vessel in the form of the pipe 19. i a tank having a threaded opening 6 in the When the lever 28 is actuated to force the top thereof. This tank is clearly shown by plunger- 24 downwardly it will be seen that way of example and does not form a part of air is drlven through the opening 13 causing the invention. The tank contains liquid as is he v lve 21 to open so that the air will flow 05 40 indicated at 7. through the pipe 19 into the top of the tank Referring to the pumping mechanism in to setup a pressure therein. As the lever detail it will be seen that the numeral 8 de- 1S swung upwardly the plunger 24 moves notes the cylinder the lower end of which upwardly and said plunger will flex to allow is open and the upper end of which is closed air to escape thereby into the lower portion 45 at 9 and has a stufiing box 10 in thecenof the cylinder 8 as will be quite. apparent. ter thereof. A head or cap 11 is threadedly Thus the setting up of a rectilinear motion engaged as at 12 on the lower openings of Of the plunger will cause the creation of a the cylinder 8 and has a central opening 13. 11 ml of pressure 111 the top of the tank bar A tubular member 1 1 extends "from the head so that the oil or like fluid 7 therein will be 59 or cap '11 and is reduced intermediate its pi ed up the extension 17 through the por- 7 ends to form a shoulder 15 and an extertlon 16, through the member 14 out through nally threaded portion 16 adapted to be enthe pipe 18. If, for any reason, it is desired .gaged with the threaded opening 6. A pipe. to release the pressure in the tank, it is only 17 depends 'from the portion 16 and is necessary to move the plunger to the bottom "0 adapted to terminate in close proximity to of the cylinder so that the pin 24 unseats the bottom of the tank 5. An outlet pipe 18 the valve 21 and then open to the spigot 32. v

vention as hereinafter claimed orsacrificing any of its advantages.

Havingt-hus described any. invention, What I claim as new 1s:-

.In a pumping mechanism of thecla-ss described,,-1the combination of .a cylinder, at 20 plunger slidable in the cylinder, :a "hollow plunger rod connected with the plunger and extending through one end of the cylinder to terminate exteriorly' thereof, means for reciprocating the hollow rod, a manually "operable valve at the outer end of the hollow plunger rod, a .ehec-kxvalve in the other end of the cylinder, a pin extending from the plunger in an 'opposite direction to the rod to engage the check valve for, unseating the same when the plunger approaches the check valve closely so that the manually operated valve may be opened to Val-lowca vent ,ipass-age therethroughland through :the hollow plunger rod and the eheck'valve.

In -'testimony whereof I iafiix my signature.
